What is the bug?

1. In the fr_CA properties files, some strings contain single quotes.
2. When a FreeMarker file declares a variable with such a string, it cannot escape the single quotes.
3. Hence, when JavaScript further declares such a variable by using singles quotes, this might cause an unbalanced quotation error.

What does this pull request do?

1. Whenever a fr_CA custom FreeMarker file substituted single quotes to double quotes, that sustitution was reported in the equivalent core FreeMarker file (see also [DRAFT] Replacing singles quotes with double quotes in FreeMarker files VIVO#178)
2. If there was no further customization in the fr_CA FreeMarker file, it was deleted (see [DRAFT] Removing custom fr_CA FreeMarkerfiles that have no diff with core files Vitro-languages#25 and [DRAFT] Removing custom fr_CA FreeMarkerfiles that have no diff with core files VIVO-languages#60 ).

Note: https://jira.lyrasis.org/browse/VIVO-1842 called for an exhaustive replacement of all the single quote to double quotes in the core FreeMarker files. This PR fixes only the one that would cause a bug.

How should this be tested?

Those modifications affect a great number of files, and a general checkup should be performed.
